New link between the RNA polymerase II-CTD and replication stress

Mol Cell Oncol. 2021 Apr 18;8(3):1910008. doi: 10.1080/23723556.2021.1910008.


Conflicts between transcription and replication are a major source of replication stress. Our recent findings show that proper dephosphorylation of Serine 5 in the carboxy-terminal domain (CTD) of DNA-directed RNA polymerase II subunit RPB1 is needed to prevent such conflicts in human cells.
